Gear pump BEKA® ES-AS

oilfluid greasestationary

The BEKA® ES-AS Series is a complete range of gear pumps to automatically lubricate lubrication points with fluid grease or oil. The ES-EA Series is a single-line system and is available with a wide range of reservoirs or as a gear pump only, without a reservoir. Working principle The lubrication system is activated by an external control unit. The pump sucks the lubricant from the reservoir and supplies it into the line system until the pressure switch responds. The connected metering injectors pass on lubricant each time the pressure builds up. When the lubrication process has finished, pressure in the system is relieved via the pressure relieve valve. The ES-EA Series systems are completed with the single line metering injectors DVB-1-2-3 or the Z31-DV. System overview Gear pump All pumps in the ES-EA Series are equipped with a gear pump. The output rate differs between the ES and EA-range. The ES range has an output of 0,4 litre per minute, while the output for the EA range differs from 0,4 up to 2 litres per minute. Low level switch The low level switch protects the lubrication system and the machine which has to be lubricated against damage resulting from a lack of lubricant. Depending on the need, the low level switch can be used for switching off the lubrication system, the machine or for actuating a visual or audible alarm signal. Filling and ventilation filter Filling the pump happens via the filling connection with an integrated filter at the top of the reservoir. Due to the filter the conveying medium is filtered from heavy contamination before it ends up in the reservoir.
